Abstract
A layered stack that can be used as an oxidation and chemical barrier with superalloy substrates, including Ni, Ni—Co, Co, and Ni-aluminide based substrates, and methods of preparing the layered stack. The layer system can be applied to a substrate in a single physical vapor deposition process with no interruption of vacuum conditions.
